Abstract

A bicycle stem is described that includes steering column clamping end portion, a hollow tubular portion and handlebar clamping end portion. The steering column clamping end portion is configured to be coupled to a bicycle steering column. The hollow tubular portion extends from the steering column clamping end portion to the handlebar clamping end portion. The handlebar clamping end portion is configured to be coupled to a bicycle handlebar. The handlebar clamping end portion includes two horizontally aligned first handlebar abutment surfaces that are laterally spaced apart relative to a center axis of the hollow tubular portion. The handlebar clamping end portion also includes a first arc shaped wall section extending between the first handlebar abutment surfaces with the first arc shaped wall section having a first convex exterior surface and a first concaved interior surface.
